Run this command in any project set up with shadcn.

Added the @loadercn registry? Use the short form:

Then add it to your interface:

import { ClassicCircularTail } from "@/components/ui/classic-circular-tail"

<ClassicCircularTail size={48} speed={1.6} />

Inherits text color. Accepts className, style, and a custom loading label. Respects reduced-motion preferences.

import type { CSSProperties, ComponentProps } from "react"

export type ClassicCircularTailProps = ComponentProps<"span"> & {
  size?: number
  /** Duration of one complete cycle, in seconds. */
  speed?: number
  label?: string
}

export function ClassicCircularTail({
  size = 40,
  speed = 1.6,
  label = "Loading",
  className,
  style,
  ...props
}: ClassicCircularTailProps) {
  return (
    <span
      role="status"
      aria-label={label}
      {...props}
      className={["classic-circular-tail-loader", className]
        .filter(Boolean)
        .join(" ")}
      style={
        {
          width: size,
          height: size,
          "--loader-size": `${size}px`,
          "--loader-duration": `${Math.max(0.1, speed)}s`,
          ...style,
        } as CSSProperties
      }
    >
      <span aria-hidden="true" className="classic-circular-tail-loader-body">
        <span />
      </span>
      <style>{`
        .classic-circular-tail-loader { display: inline-flex; flex-shrink: 0; }
